WEIGHING APPARATUS FOR LIQUIDS.

Specification of Letters Patent.

Patented Apr. 22, 1913.

Application filed May 23, 1911. Serial No. 629,060.

To all whom it may concern Be it known that I, J osnrn MEYER, a subjectof the King of Prussia, and resident of Berlin, Germany, have inventednew and useful Improvements in \Veighing Apparatus for Liquids, of whichthe following is a specification.

This invention relates to an apparatus by which liquid may automaticallybe weighed.

The invention consists in the peculiar construction of the apparatuswhereby the friction of its single parts is reduced to the utmost limit.

My invention is illustrated on the accompanying drawings in which Figurel is an elevation of the apparatus partly in section, Fig. 2 is amodification, and Fig. 3 shows in an enlarged scale the supply valve.

WVith reference to the drawings a is the weighing vessel. The same, withits neckand base-portion, by means of two clamps b is fastened to avertically movable L- shaped frame 0. Through the neck opening d of saidvessel a there passes the inlet pipe 6 for the liquid to be weighed.This pipe (Fig. 3) is provided at its top-end with a valve 1 which maybe opened by an upward movement of a rod 9. The outlet a of the vessel ais controlled by a floating cone h preferably formed of glass.

At its upper end the L-shaped frame 0 is kept in position by an arm 2'the other end of which is pivoted to the frame is of the apparatus at 76The lower end of the L- shaped frame 0 is held by means of a lever Z.This latter is pivoted to the frame is at 7: The free arm Z of the leverZ may be caught with its upright end on by means of a hook m controlledby a lever 02. The free end of the latter movably passes a coin channel0 of well known construction.

The weight of the vessel a and that of its parts is balanced by a numberof counterweights p arranged upon a scale beam 'Q pivoted to the frameis at k The free arm of the scale beam (1 is in connection with theL-shaped frame 0 by means of a link 1'.

The vessel on (Fig. 2) advantageously is closed by a cover 8 providedwith a central sleeve 8 sliding along the pipe 7.

The apparatus operates as follows: The liquid to be weighed enters thestud e of the pipe 6. The entrance of the latter is closed by the valve7. A coin is put into the channel 0. This coin is prevented from passingsaid channel 0 by the free end of the lever a, and by the weight of thecoin the lever a is pressed down. The other end of the lever a lift-sthe free end of the angular lever m and thereby the end m of the lever ZZ is freed. Under the action of the counterweights 7? the L-shapedframe. 0 with the vessel a now is lifted. The top of the cone 7Lcontacts the lower end of the rod 9 whereby the valve f is opened. Theliquid now enters the pipe 6 and runs into the vessel 04 until thelatter is lowered by the weight of the liquid flowing in. On thislowering movement of the vessel a the valve f is again closed, and thecone h floats so that the liquid flows off through the outlet 0 In thisparticular portion the pipe Z is surrounded by a shell Z provided withan inlet pipe Z and a number of outlet openings Z for the purpose ofenabling the cleansing or .washing of the vessel a by means of a waterspray.

Having now described the nature of my invention what I claim is 1. Inmeans for automatically weighing liquids, in combination, a weighingvessel open at its upper and lower ends, a vertically movable supporttherefor, movable guiding arms engaging the upper and lower ends of saidsupport, a lever provided with counterweights operatively connected tosaid support, an inlet pipe passing through the opening in the upper endof said vessel, avalve therefor, a floating cone normally closing thelower opening of said vessel, and means actuated by said cone as thevessel is raised to open said valve.

2. I11 means for automatically weighing liquids, in combination, aweighing vessel open at its upper and lower ends, means for moving saidvessel vertically, an inlet pipe provided with a valve and passingthrough the upper opening of the vessel, a valve rod In witness whereofI have hereunto set passing through said pipe and projecting my hand inthe presence of two Witnesses. from the lower end thereof, and afloating JOSEPH MEYER cone normally closing the lower openlng of thevessel and adapted to engage the lower Witnesses:

end of said valve rod to open said valve as HENRY HAsPER,

the vessel is raised. WOLDEMAR HAUPT.
